Headgear for use in the pap field

Abstract

A headgear for use in the Positive Airway Pressure field includes an inner layer, a bonding layer, a padding layer, film layers, and an adhesive. The inner layer is configured to be at least partially in contact with a patient's skin during use, while the bonding layer is configured to adhere an outer side of the headgear, which comes into contact with the air, to a fixed part by folding the headgear, thereby tightening or loosening the headgear. The padding layer, placed between the inner layer and the bonding layer, increases thickness. The film layers are provided between the inner layer and the padding layer, as well as between the padding layer and the bonding layer. The adhesive is configured to bond the layers together. The headgear has at least three layers and is made of at least two types of textile materials.
